12 October 1984,
Margaret Thatcher was saved from the IRA attack shortly afterwards. The Conservative Party conference was being held at the Grand Hotel in Brighton, where the IRA caused a powerful bomb. It caused five deaths and the UK prime minister managed to survive. The IRA published the following statement (from the Devil’s School website): "Mrs Thatcher now discovers that Britain cannot occupy our country, torture our prisoners and shoot our people in their streets and flee. We have had bad luck today, but remember that we should only be good once. You will always have to be lucky. It gives peace to Ireland and there will be no war."
